        //使用JavaMail发送邮件的5个步骤

        //1.创建定义整个应用程序所需的环境信息的Session对象
        Session session = Session.getDefaultInstance(prop, new Authenticator() {
            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                //发送邮件用户名，授权码
                return new PasswordAuthentication("2295047199@qq.com", "xgqivrbqjpvtdidg");
            }
        });
        //通过session的debug模式，这样就可以查看到程序发送Email的运行状态
        session.setDebug(true);

        //2.通过session得到transport对象
        Transport ts = session.getTransport();

        //3.使用邮箱的用户名和授权码连上邮件服务器
        ts.connect("smtp.qq.com", "2295047199@qq.com", "xgqivrbqjpvtdidg");//授权码

        //4.创建邮件:写邮件
        //注意需要传递session
        Message message = new MimeMessage(session);
        //指明邮件的发件人
        message.setFrom(new InternetAddress("2295047199@qq.com"));

        //指明邮件的收件人，现在发件人2295047199，收件人  通过获取
        message.setRecipient(Message.RecipientType.TO,new InternetAddress(emailAddress));
        //邮件的标题
        message.setSubject("只包含文本的简单邮件");
        //邮件的文本内容
        message.setContent("<h1>你的密码是：</h1><p style='color:red'>"+123+"</p>","text/html;charset=UTF-8");

        //5.发送邮件
        ts.sendMessage(message,message.getAllRecipients());

        //6.关闭连接
        ts.close();
    }
